Door Locking Solenoid

corner of the washer.
Door Locking Gear Motor Assembly
(Newer Models)
The door locking gear motor is rotated shut with
control voltage to lock the door and releases when
voltage is removed. It is located in the left front
corner of the washer. (Original locking solenoid
models can be converted to the new assembly)

Thermoactuators

The thermoactuators are a safety device that
keeps the door from immediately unlocking if
power is lost while the machine is operating. They
are mounted under the door locking solenoid.

Lock Thermoactuator

Control voltage is applied to the lock
thermoactuator at the beginning of the cycle
making it extend and block the door locking
solenoid. This keeps the door locked for
approximately two minutes after a power failure
occurs. The lock thermoactuator does not delay
the door opening at the end of a normal cycle.

Unlock Thermoactuator

To insure that the lock thermoactuator has
retracted by the end of the cycle, one minute prior
to the end of the cycle, the unlock thermoactuator
is powered with control voltage making it extend
and unblock the door locking solenoid.

Drive Belt Removal

Turn the drive belt(s) off the basket pulley first and
then remove from the motor pulley.
Reverse this procedure for installation.
